Title: Construction of bending and caulking die
Inventor: ABE TSUKASA
IPC: B21D11/20
Filed: 1983-01-25
Abstract: PURPOSE:To improve quality with a reduced initial cost and lessened labor for replacing materials by performing bending and drawing during one time of pressing with a top die by a space holding means provided above the punch plate of a top die. CONSTITUTION:When a material 11 is placed between a bending punch 5 and a knock-out 9 and a holder plate 2 is lowered, the punch 5 bends the material 11 to the desired shape of a bending die 6. The inclined part 3a of a timing plate and the inclined part 13a of a cam contact with each other and the plate 3 moves leftward while contacting with the space holding part 15b of a stopper 15. The part 15b goes into the hole 3b of the plate 3 but the advance thereof is blocked by a spring 14 in the stopper 15. Thereupon the step part 7d of a die holder and a knock-out 9 contact with each other and the leftward movement of the plate 3 and bending are completed. When the plate 2 descends further, the inclined part 17c of a cam and the inclined part 12a of a drawing punch 12 contact with each other, and the punch 12 moves horizontally, thereby drawing the material 11 to a desired shape. The spring 14 is then pushed and contracted and the holding part 15b intrudes into the hole 3a and therefore the space 19 is narrowed and the punch plate 14 is prevented from descending.

Next, the resin film 1, onto which the ceramic layer 2 is laminated, is housed between molds 4 and 5 under the condition that the film closely contacts the bottom face of the female mold 4. After the molds 4 and 5 are closed, molten resin material is injected from an injection molding cylinder 6 through a hole 7 to the clearance in the molds so as to laminate a resin molded layer 3 to the spray surface 2b of the ceramic layer 2 by injection molding. Next, the resin film 1 is separated from a resin item 9 so as to expose the surface 2a of the ceramic layer 2. Since the surface 2a is formed along the form of the one surface 1b of the resin film 1, the surface 2a has a smooth surface.
